so i'm getting ready to do a complete overhaul of my front and rear suspension. i have some delimmas to sort out before i get started as i'm still rather new to xj's, and was wondering if ya'll might be able to help.

i have a 91 xj 4.0 that i am in the process of completely rebuilding. just installed a reman motor 1500 miles ago, now its time for the suspension. right now it has a 4 inch fabtech lift kit on it, sporting 31x10.5's the entire front end is shot so i'm going to start fresh with a rubicon express 4.5 inch super flex kit with rear springs. i will be upping tire size to 32x11.5's with cragar soft 8's.

re's website "highly recommends" adding sye and cv driveshaft with this kit. are an sye and cv driveshaft absolutely necessary for this kit? rig is 90% daily driver, so i'm wondering, if these parts are indeed necessary, will i be able to get by with the kit without them for a couple months until i have money for them? i already have a bad case of the death wobbles, i don't want to deal with it after spending all this cash...the lift kit, shocks, wheels and tires are all i can budget this time around, as they are in desperate need of replacement. once my tax money is in i will be rebuilding or replacing the axles and would prefer to deal the sye and cv driveshaft then if i can get by for awhile.

also wondering where i might be able to find info on what type of tranny (5 speed) i have, as well as the transfer case, axles and gearing?

thanks in advance for any input you guys might have.

If you wanna go over a 3.5" lift you need the SYE to eliminate any binding or dropping your ds when you flex out, but if your easy on it you could get away with a transfercase drop kit till you get the SYE...

 

cool. thanks very much for your response. that's what i was hoping to hear.

anyone know of a site that has a breakdown of types of trannies/transfer cases by year of xj?
